Are they pekins? If so, I don't keep them I'm afraid, so don't take my word for it, but I think the bird on the left in Photo1 is a boy, and the one in the foreground may be as well. I can't see the 2 in the background clearly enough. A few better head shots would help, but depending on age you may need to wait a little while longer. How old are they?

17 days at time of taking picture. The grey one seems to act like a boy and has done since birth, taking the highest point and always been the bravest. Think the 2 in the middle may be boys because they spar with the grey one, but may just be chicks fighting? The blonde on the right is the quietist and keeps to herself. Definitely the most gentle of the four. Hoping I don't get 3 boys, not sure what to do with a lone girl

I seem to remember it being about 4 weeks when the boys properly start showing combs and wattles BB but when they do fortunately it's pretty obvious and they are nice and red unlike a lot of the other breeds, if I was taking a stab at it I would go along with MrsBiscuit just based on the combs. They are lovely little chicks whatever they turn out be.

They are all very sweet and come from lovely looking parents (although not 'standard' breed colours). Sadly I only have a garden and although neighbours love the girls and appreciate the care I take to make sure they are clean and do not attract vermin etc, I think cockerels would be one step too far and will need to find homes or put them down
They are all hand tame already and the grey one is a great charector. Will be sad to seem him go as saved his life the day he hatched when he got caught in mums feathers and nearly died.
